Verify Factura Electronica Chile SII (iso-8859-1)

See more XAdES Examples

Demonstrates how to verify SII XML stored as iso-8859-1 having just a single signature. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // The signed XML to be verified in this example contains the following:

    // <?xml version="1.0" encoding="ISO-8859-1"?>
    // <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
    // <Documento ID="F13T34">
    // ...
    // </Documento>
    // <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
    // ....
    // </Signature>
    // </DTE>

    // Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
    CkStringBuilder sbXml = new CkStringBuilder();
    success = sbXml.LoadFile("qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1");
    if (success == false) {
        Log.i(TAG, "Failed to load input file.");
        return;
        }

    CkXmlDSig dsig = new CkXmlDSig();

    success = dsig.LoadSignatureSb(sbXml);
    if (success != true) {
        Log.i(TAG, dsig.lastErrorText());
        return;
        }

    boolean bVerifyReferenceDigests = true;
    boolean bVerified = dsig.VerifySignature(bVerifyReferenceDigests);
    if (bVerified == false) {
        Log.i(TAG, dsig.lastErrorText());
        return;
        }

    Log.i(TAG, "Signature verified = " + String.valueOf(bVerified));
